Inductive
displacement transducers of this series measure linear
displacements and indirectly all mechanical values
convertible into distances by additional equipment
(i.e. tension and compression forces, extension,
torque, vibration).
The sensor body equipped with a connector has an outer
diameter of only 8 mm and therefore is especially well
suitable for the integration in dimensionally
restricted structures.
Typical application fields are displacement and
extension measurements on

| Description |
 |
The
cylindrical case made of stainless steel, houses a
differential transformer (LVDT). It consists of a
primary and two secondary coils with axially movable
cores.
A displacement of this core changes the magnetic
induction of the coils. The IN-LINE carrier frequency
amplifier converts the displacement into a direct
proportional electrical DC voltage.
The transducer is constructed as a probe at which
within the measuring range a spring pushes the probe
tip towards the measuring object. Bellows protect the
mechanical guidance of the probe tip against pollution.
The IN-LINE amplifier is integrated in the connector
cable and adjusted to the transducer. Both components
form a unit while they can be separated for mounting
purposes (miniature plug connection at the transducer).
The sensor body is separated galvanically from the
supply and the measuring signal.
